Dear Dr. Avinoff:-

I was delighted to receive the pterosaur casts which arrived yesterday in good condition. Please advise us as to the value of these casts so that we can enter them in our exchange account.

In coloring the casts we are somewhat in doubt about the colors of the matrix and the bone in the cast of Camphylognathus [sic] #1124. Will you please have Sidney [sic] Prentice send a sample color of the matrix and one of the skeletal bones. He can send us a sample color on paper approximating the colors of the specimen and of the matrix.

The work of Tyrannosaurus has proceeded more rapidly than anticipated and the specimen will be ready by November 1st, so that you can now make calculations accordingly, letting us know approximately what day we may expect the truck.

As ever,
Sincerely yours,
Barnum Brown

Notes for Dr. Brown:

See people making Carboniferous restoration for plants and casts to be used in our restorations.

Also learn about disposition of Permian material for description and possibilities of casts.

See especially:
Nyctosaurus skeleton #11422 and any other specimens from the Bayer [Bayet?] collection that could be acquired.
